In the inside of the toilet bowl flush device 10 of present embodiment, be provided with as the motor 42 of drive source and as 5 grades of gears 43～47 of deceleration device 41.The turning moment of the 4th grade of gear 46 is exported by the 1st output shaft 70.The turning moment of the 5th grade of gear 47 is by 72 outputs of the 2nd output shaft.As motor 42, if use when the brush type high-speed motor of DC24 volt work, the speed reducing ratio from the 1st grade to the 4th grade can roughly be made as about 1/100.The speed reducing ratio of the 5th grade of gear then can easily be applicable to various low level cisterns if roughly be made as about 1/2.

Again, mandrel 22 is provided with mandrel back-moving spring 52, is neutral condition and suppress.Similarly, also be provided with reset gear spring 53 on the 4th grade of gear 46, quilt is suppressed is neutral condition.

In addition, when the manual operation of using operating handle 100, in order to prevent to be subjected to the cogging torque (cogging torque) that motor 42 is applied, the 4th grade of gear 46 is combined into respect to mandrel 22 and has specific idle running angle.

Figure 14 is the ideograph that combines section that shows the 4th grade of gear 46 and mandrel 22.That is to say, dispose mandrel 22 at the heart of the 4th grade of gear 46.Mandrel 22 combines with operating handle 100 and the 1st output shaft 70.And, in the outside of this mandrel 22 and the inner face of gear 46, be respectively arranged with protuberance 22P, 46P.What Figure 14 showed is neutral condition, by this state with mandrel 22 (also being operating handle 100) when the direction of arrow rotate, in the scope till this protuberance 22P retaining is received the protuberance 46P of gear 46, mandrel 22 can be different from gear 46 and independent the rotation.That is to say that in this scope, mandrel 22 can not be subjected to the effect of cogging torque that motor 42 applies, power that reset gear spring 53 applies and rotate.So, can carry out manual operation by operating handle 100 trippingly.

On the other hand, when being subjected to motor 42 and driving, gear 46 just dallies towards the direction of arrow from neutral condition shown in Figure 14, when this protuberance 46P retaining is received the protuberance 22P of mandrel 22, just combines with mandrel 22 and makes moment be communicated to output shaft.That is to say that the scope till protuberance 46P retaining is received protuberance 22P is set as the idle running angle.

Secondly, the drive circuit that makes so toilet bowl flush device 10 drivings is described.

Figure 15 shows to allow the ideograph of the drive circuit that the motor 42 of toilet bowl flush device 10 drives.This drive circuit for example, can contain in the aforementioned drive division 520 of Fig. 4 to Fig. 7.

The shown drive circuit of Figure 15 has: be used for controlling the switch element Tr1～Tr4 of the direction of rotation of motor 42 and rotation amount, diode d3 and the d4 that prevents overcurrent to flow through the thermistor 71d with positive ratio characteristic of motor 42, the reverse exciting current when making braking control etc. can not be applied to employed diode d1 such as the CPU that contains at drive division 520 and operating portion 510 etc. and d2 and be used for forming the current lead-through path when braking is controlled.

For example, when allowing motor 42 just change, making switch element Tr1 and Tr4 is opening, and Tr2 and Tr3 are closed condition, and makes its when counter-rotating, and making Tr1 and Tr4 is closed condition, and switch element Tr2 and Tr3 are opening.

On the other hand, force when moving when motor 42 is imposed, any of switch element Tr3 or Tr4 is closed condition for other switch elements of opening.For example, allowing after 42 in the motor rotation specified quantitative, when under situation like this, braking, by containing in the elastic force of the reset gear spring 53 and the mandrel back-moving spring 52 of toilet bowl flush device 10, make the mandrel rotation of motor 42, and desire to be returned in the shown neutral position of Figure 14.At this moment, because the effect of motor 42 starter/generators, so by its current excitation magnetic field performance regeneration braking effect.By diode d1 and d2 are set, can prevent that this reverse exciting current from putting on CPU that contains in control part 500 grades etc.

On the other hand, when applying the situation of weak braking, all switch element Tr1～Tr4 are closed condition and get final product.Just, can obtain the braking action that the cogging torque (cogging torque) of motor 42 is produced during this situation.

If incite somebody to action when so switch element Tr1～Tr4 is set as suitable opening, can carry out rate of load condensate (duty) control by pulse width modulation mode (PWM:pulse width modulation).

That is to say, when switch element Tr1～Tr4 is driven respectively, can control rotary speed by pulse type conductive waveform (for example, DC24 volt) shown in Figure 16.For example, making just changes or the cycle G when reversing is 1 millisecond (PWM drives cycle 1kHz), and the cycle G during braking is 8 milliseconds (PWM drives cycle 125Hz).At this, so-called " ON-rate of load condensate H% " be illustrated in shared opening in 1 cycle (G millisecond) during be H%.For example, G=1 millisecond, H=30% are illustrated in and have only 0.3 millisecond (1 millisecond * 30%) to be opening in 1 cycle.

Below, illustrate according to the rinse mode specific embodiment of the type of drive of switching motor 42 suitably.

Just, relevant Fig. 3 as previously mentioned, the output shaft that makes toilet bowl flush device 10 is (CW) or counterclockwise during 1 second left and right sides of (CCW) rotation toward the clockwise direction, can be 100% to allow motor 42 drive with rate of load condensate.At this moment, motor 42 is endowed maximum driving force, can promptly allow output shaft rotate and implement big flushing.

For this, as the narration of the relevant Fig. 3 of preamble, when carrying out the little flushing of the maintenance action must have about 4 seconds, though can be 100% successional drive current to be supplied to motor 42 continuously with rate of load condensate, but in the middle of during keeping, motor 42 also might generate heat.When situation so, it is desirable to utilize PWM to control supply capability.

Figure 18 shows to import PWM control, carries out the flow chart of the specific embodiment of little maintenance action in 4 seconds.

In this situation, at first, in step S22 and S23, implement 1 second rate of load condensate be 100% driving.Thus, the output shaft of toilet bowl flush device 10 promptly rotates to till the holding position of little flushing.Then, in step S24 and S25, utilize PWM to control and carry out the motor driving.That is to say that the driving rate of load condensate of step S24 makes motor 42 can resist the elastic force of mandrel back-moving spring 52 and reset gear spring 53 and keep the electric power of the state degree of opening valve under little flushing state as long as supply with.Particularly, for example, can be 80% in the driving rate of load condensate of step S24.So implement,, can prevent that also motor 42 is overheated even little flushing state was kept for 4 seconds.

Moreover, also can utilize braking control motor 42 to keep action to carry out little flushing.

Just, at first, in step S32 and S33, implement 1 second rate of load condensate be 100% driving, the output shaft of toilet bowl flush device 10 is promptly rotated to till the holding position of little flushing.Then, in step S34 and S35, close element Tr3 or Tr4 is opening by getting out of the way, to carry out powerful regenerative braking control.Thus, motor 42 is controlled by the braking of the elastic force of antagonism mandrel back-moving spring 52, reset gear spring 53, and slowly gets back to neutral condition (in the shown state of Figure 14).Therefore, can make the draining valve of low level cistern continue to open, substantially be achieved and the identical action of little maintenance action.And, in this case, during step S34 and S35, so do not have overheated situation owing to the electric power that does not come from the outside is fed into motor 42.

Figure 20 shows the flow chart of forcing the specific embodiment of moving control by rate of load condensate control.

Just, imposing at step S44 and to force when moving, as illustrated in Figure 16, is to control by rate of load condensate that to make switch element Tr3 or Tr4 be opening.By suitably selecting rate of load condensate, just can fine control braking strength, and the output shaft that can suitably control toilet bowl flush device 10 is returned to the speed till the neutral condition (state that Figure 14 is shown).Thus, can fine regulate the discharge under the little flushing maintenance action, to improve the water-saving effect.

In step S52 and S53, implement 1 second rate of load condensate be 100% driving, allow the output shaft of toilet bowl flush device 10 promptly rotate to till the holding position of little flushing.Then, make all switch element Tr1～Tr4 all become closed condition, utilize the cogging torque (cogging torque) of motor 42 to carry out weak braking control at step S54.In this situation, motor 42 also is the braking control by the elastic force of antagonism mandrel back-moving spring 52, reset gear spring 53, and slowly gets back to neutral condition (in the shown state of Figure 14).Therefore, can make the draining valve of low level cistern continue to be unlatching, substantially realize little maintenance action.Carry out the moving control of pressure shown in Figure 19, still will carry out weak braking control shown in Figure 21, can consider that the elastic force pressure of back-moving spring 52,53, little flushing keep flushing water flow necessary in the action etc. and suitably decision.

Figure 22 shows the flow chart of controlling the concrete example that carries out weak braking control by rate of load condensate.That is to say,, switch element Tr1～Tr4 in mode shown in Figure 16, is made it to be closed condition by rate of load condensate control at step S64.In this case, also can fine control brake force by suitably selecting rate of load condensate, the output shaft of suitably controlling toilet bowl flush device 10 is returned to the speed till the neutral condition (being shown in the state of Figure 14).Thus, fine be adjusted in the discharge that little flushing keeps action, and can be improved the water-saving effect.

More than be that explanation is suitably changed the specific embodiment of the control of motor 42 according to rinse mode with reference to Figure 17 to Figure 22.But the present invention only is confined to these specific embodiments.For example, in keeping action, also can force moving and weak braking to be combined, in addition, also can be with the arbitrary braking in these, with the just commentaries on classics of motor 42 or reverse to drive and do appropriate combination.

Figure 23 is the stereogram that is presented at the state that possesses the toilet flushing system that present embodiment is installed on the water-closet for bowl that " right handle-type " low level cistern 200 is arranged.Figure 24 is an ideograph of being observed the inside of this low level cistern 200 by the top.

The toilet flushing system of present embodiment has structure shown in Figure 6, possesses operating portion 510 that remote control is arranged, contains drive division 520 and toilet bowl flush device 10 in toilet seat 400.

Figure 25 and Figure 26 are the ideographs that is connected that shows toilet bowl flush device 10 and toilet seat 400.

Be provided with connector 402 at the place, the back side that is set at the toilet seat 400 on the closet 300.And, be connected in the connecting line 76 of the toilet bowl flush device 10 that is accommodated in the low level cistern 200, draw from the transpiration hole 290 at the back side that is arranged on low level cistern 200, make the attachment plug 78 of its front end be connected in the connector 402 of toilet seat 400.

On toilet seat 400, contain not shown drive division 520, for example,, can suitably control the action of toilet bowl flush device 10 by the driving signal of suitable supply DC24 volt.That is to say that the user need not the operating handle 100 of operation setting on low level cistern 200, and the portable switch (operating portion 510) that suitably is arranged on by operation on the remote control of wall between hand washing etc. just can make the flushing water swash of wave in closet, very convenient.

On toilet seat 400 (control part 500), human inductor is set, for example, when the user near the time, or when taking toilet seat 400, can allow toilet bowl flush device 10 actions in the mode that the swash of wave prepares flushing water.That is to say, before closet 300 is used, earlier makes its inner face become moisture state, can suppress the attached work of dirt etc. and feel more cleaning by swash of wave preparation flushing water.

On the other hand, by human inductor, when the user leaves, or in erecting from toilet seat 400, can allow toilet bowl flush device 10 actions in the mode of closet 300 automatically to make the flushing water swash of wave.So, then can become what is called " flushing automatically ", thereby even can realize for good toilet flushing systems also easy to use such as old man, physical disabilities person or children.

Moreover so toilet seat also can make up so-called local douche device.Just, be sitting in the device of the user part of toilet seat 400 in the assembling with water (warm water) flushing, then more can realize the toilet flushing system of high function and usability excellence.When this kind situation, for example also can allow toilet bowl flush device 10 move in the mode of corresponding swash of wave flushing current with the end of a period of local douche.

Figure 27 and Figure 28 drive the assembling drawing that is installed on the 1st output shaft 70 with part with valve; Figure 29 and Figure 30 are the assembling drawings that this toilet bowl flush device is installed on low level cistern 200.

At first, as shown in figure 27, the 1st output shaft 70 is fixing with mandrel 80 by screw 81.Moreover, as shown in figure 28, separator 82 is inserted this mandrel 80 also fix, and near its front end,

pelletron bar

84,85 is installed respectively by pin (E shape ring) 86 by pin (E shape ring) 83.

Then, as shown in figure 29, make screw lock protuberance 20 outstanding, by

pad

90 and 91 and utilize under the state of nut 92 with clamping low level cistern 200 outer walls and fix from the opening 202 of low level cistern 200.And, as shown in figure 30, stop part 93 is fixed in the front end of mandrel 22 by screw 94, be pressed into from it and the operating handle 100 of fixed manual operation usefulness.

In addition, as shown in figure 31,, be fixed with an end of pelletron 220,230 respectively at the front end of the

pelletron bar

84,85 that outstanding separator extends below vertical with horizontal direction from low level cistern 200.At the other end of this pelletron 220,230, as shown in figure 23, be connected on the draining valve 250 of the draining valve 240 of upside and downside, by with its pull-up, make the flushing water swash of wave to closet 300.

At this, this low level cistern 200 shown in figure 32, has the rinse mode that action bars 100 (CW) rotation is toward the clockwise direction carried out " big flushing " and carried out " little flushing " towards (CCW) rotation counterclockwise.The both is instantaneous execution, need not be kept.

Corresponding to this, pelletron bar 85 has specific idle running angle with respect to separator 82.That is to say, shown in the insertion figure among Figure 23, when output shaft 70 during towards the rotation of the direction (CW) of arrow A,

pelletron bar

84 and 85 boths rotations and drawing pelletron 220,230 is all opened the draining valve 240 of upside and the draining valve 250 of downside.Thus, make the flushing water of " greatly " flow into closet 300.

On the other hand, among the insertion figure in Figure 23, when output shaft 70 towards the direction (CCW) of arrow B when only rotating special angle, pelletron bar 84 is interlock and rotating with it, but pelletron bar 85 for idle running still towards vertical below.Its result has only pelletron 220 by drawing, and only opens the draining valve 240 of upside.Thus, make the flushing water of " little " flow into closet 300.

So, be " CW " with " big flushing "; " little flushing " is the rinse mode of " CCW ", for example, and with its preset value (initial setting) state as the toilet flushing system of present embodiment.That is to say,, just can not need to carry out the operation of the initial setting of remote control 510 if when toilet bowl flush device 10 is installed on the low level cistern of this kind form.

Secondly, describe at situation about toilet flushing system of the present invention being contained on the water-closet for bowl that has with above-mentioned different rinse modes.

Figure 33 is installed in toilet bowl flush device 10 of the present invention the ideograph of the state on the have different rinse modes low level cistern 200 of " right handle-type ".

This low level cistern 200 has single draining valve 240 and is connected in the pelletron 220 of this draining valve.

Figure 35 is the ideograph that is used for illustrating the rinse mode of low level cistern 200.Promptly " big flushing " is with bar 100 (CW) rotation toward the clockwise direction; " little flushing " is to implement by the mode that bar 100 is kept after (CCW) rotation counterclockwise.When toilet flushing system of the present invention is installed on the water-closet for bowl with rinse mode like this, carry out the initial setting operation by remote control 510.

Figure 36 is the ideograph that shows an example of initial setting operation.

That is to say, at first, " stopping " switch 511 of being located on the remote control 510 is pressed by more than 10 seconds.Thus, the liquid crystal display 512 of remote control 510 just starting point go out.This point goes out and represents to have entered the switch mode that is used for switching rinse mode.Secondly, " little " switch on the remote control 513 is pressed by more than 5 seconds.Thus, by the drive division 520 that is arranged on toilet seat 400 sound " serge serge " sound.This is in calcspar shown in Figure 6, and the rinse mode determination section 520A basis of drive division 520 has been switched the signal that rinse mode one thing is informed user or setting person from the switching signal of operating portion 510.

Then, when pressing by " stopping " switch 511 on the remote control, the point of liquid crystal display 512 goes out and just stops, and finishes the initial setting operation.

By the initial setting operation of above explanation, it is the snap action of clockwise direction rotation (CW) that toilet flushing system of the present invention is carried out out reliably when " big flushing ", is the maintenance action of rotation (CCW) counterclockwise when " little flushing ".

Figure 37 is the ideograph that shows the state on the low level cistern 200 of " the front handlebar type " that also have different rinse modes that toilet bowl flush device 10 of the present invention is installed in.

Figure 38 is an ideograph of being observed the inside of this low level cistern 200 by the top.

The pelletron 220 that this low level cistern 200 also has single draining valve 240 and is connected in this draining valve.And pelletron bar 87 is connected in the 2nd output shaft 72 of toilet bowl flush device 10.This is because in the low level cistern 200 of this form, because pelletron bar 87 is longer, so for opening water discharge valve 240, output shaft must have bigger turning moment.That is to say, in this specific embodiment, can make the turning moment of the 2nd output shaft 72 of toilet bowl flush device 10 also bigger than the turning moment of the 1st output shaft 70.

Figure 39 is the assembling drawing that the 2nd output shaft 72 that is presented at toilet bowl flush device 10 is installed the erection procedure of pelletron bars 87; Figure 40 is the assembling drawing that this toilet bowl flush device 10 is installed on the erection procedure of low level cistern 200.

During for " front handlebar type ", as shown in figure 39, fixed by the pelletron bar 87 that screw 88 is long with stroke.Installation portion at pelletron bar 87 is provided with projection 87R.This projection 87R has the effect of the portion of bearing as screw 88, and also other with being arranged on output shaft 72 sides simultaneously raised line rib 72R (please refer to Figure 10) cooperates and works as " stop part ".That is to say, receive raised line rib 72R, the rotation of pelletron bar 87 is stopped by projection 87R retaining.So, can prevent the excessive rotation of pelletron bar 87.

Relevant Figure 13 as described above, the turning moment of the 2nd output shaft 72, also bigger than the turning moment of the 1st output shaft 70.Therefore, when raised line rib 72R is set to desire to make it to do the time spent as " stop part " on the 2nd output shaft 72 sides side, it is bigger to load for the mechanicalness of raised line rib 72R, may have the anxiety of breakage.So during situation, also can use the 1st output shaft 70 to obtain the effect of " stop part ".That is, the angle limits member that will have as Fig. 9 and projection 80R shown in Figure 10 is installed in the 1st output shaft 70.Connect by raised line rib 70R and the projection 80R retaining that is arranged on the 1st output shaft 70 sides side, the rotating range of the 1st output shaft 70 is restricted.Relevant Figure 13 as described above because the 1st output shaft 70 and the 2nd output shaft 72 interlocks, so can limit the rotating range of the 2nd output shaft 72.

In addition, Figure 41 is the ideograph that is used for illustrating the rinse mode of this low level cistern 200.Promptly in this low level cistern, there is no the differentiation that " big flushing " reaches " little flushing ", all is to make bar 100 instantaneitys towards (CCW) rotation counterclockwise under any situation.When toilet flushing system of the present invention is contained in the water-closet for bowl with rinse mode like this,, for example, can carry out following initial setting operation by remote control 510.

Figure 42 is the ideograph that shows an example of initial setting operation.

That is, " stopping " switch 511 that at first will be located on the remote control 510 is pressed by more than 10 seconds.Thus, the liquid crystal display 512 of remote control 510 just starting point go out.This point goes out and represents to have entered the switch mode that is used for switching rinse mode.Secondly, " greatly " switch on the remote control 514 is pressed by more than 5 seconds.Thus, by the drive division 520 that is arranged on toilet seat 400 sound " serge serge " sound.Then, when pressing by " stopping " switch 511 on the remote control, the point of liquid crystal display 512 goes out and just stops, and finishes the initial setting operation.

Initial setting by above explanation is operated, toilet flushing system of the present invention, and its " big flushing " all is to rotate moment by counter clockwise direction (CCW) to carry out the flushing action reliably with " little flushing ".

In this case, do not distinguish " big flushing " and " little flushing " in fact, and the flushing water that all " washes greatly " with isodose flows out.At this, as shown in figure 43, also can on " little " switch of remote control 510, paste the paster of " greatly ".

Yet when initial setting operation was selected specific pattern by multiple rinse mode, if the stratum of operating sequence is dark excessively, or the number of operations of switch was when too many, just too miscellaneous.Therefore, also can when using remote control 510 to do the initial setting operation,, will operate simplicity by suitably separately using a plurality of switches.

Figure 44 shows the key diagram of simplifying the concrete example of initial setting operation by the switch that separately uses remote control 510.

In the situation of this specific embodiment, acquiescence (initial setting) state is corresponding to " rinse mode 1 ".Can for example,, enter the switch mode that switches rinse mode by under this state by " stopping " switch on the remote control 510 511 is pressed by more than 10 seconds.At this moment, as described above, can go out by the point of liquid crystal 512 etc., suitably notify user or setting person.

Under this state, for example, when pressing " little " switch 513 pressures more than 5 seconds, just can switch to " rinse mode 2 ".At this moment, by coming from " serge serge " sound of drive division 520, and switching that can affirmation mode.If when wanting to be fixed in " rinse mode 2 ", then press " ending " switch 511.

On the other hand, " little " switch is pressed by more than 5 seconds the time again, then can switch to " rinse mode 3 ".At this moment, can confirm the switching of this pattern by coming from " serge serge serge " sound of drive division 520.

So, " little " switch 511 is pressed by more than 5 seconds, just can switch according to the order of " rinse mode 1 " → " rinse mode 2 " → " rinse mode 3 " → " rinse mode 4 " → " rinse mode 1 " by every.

Similarly, in switch mode, " greatly " switch 514 is pressed by more than 5 seconds, just can switch according to the order of " rinse mode 1 " → " rinse mode 5 " → " rinse mode 6 " → " rinse mode 7 " → " rinse mode 1 " by every.At this moment, also can suitably send and be used for sound that affirmation mode switches etc. from drive division 520.

So, in the present invention, by suitably separately using the switch of remote control 510, for example, the switching of the rinse mode of 7 kinds, maximum as long as just can implement by 5 switching manipulations.

At this moment, implement, can paste manual in advance at remote control 510 in order to make initial setting processing ease ground.

Shown in Figure 46 (b), stick on the remote control 510 by the description 600 that will record the initial setting operating sequence, can make the initial setting processing ease and carry out reliably.In addition, when initial setting is operated, also can be in the middle of the Switch that is arranged at remote control 510, as long as operation " stopping " switch 511, " little " switch 513 and " greatly " switch 514.At this, if having only these switches and liquid crystal 512 to be shown in the surface, and the mode of hiding other switch designs description 600, then can be very easily and carry out the initial setting operation reliably.

After a series of initial setting operation ends, these description 600 are taken off from remote control 510, the user just can carry out common use.

And, according to the present invention, in advance any kind in the multiple rinse mode is stored (depositing) at control part 500, by selecting these one of them and make it action, can be applicable to existing various low level cisterns.Therefore, the low level cistern that the user need not more renew is installed toilet bowl flush device 10 on the low level cistern of existing setting, is operated by carrying out specific initial setting by control part 500, thereby can import toilet flushing system.Its result can realize aforementionedly having with various functions headed by the automatic flushing and easy-to-use water-closet for bowl with low cost, and is very convenient.

The form of low level cistern not simultaneously, when this rinse mode was different, the structure in the low level cistern was also scarcely identical.Therefore, if be made into the setting angle that can suitably regulate toilet bowl flush device, the distance between till the pelletron bar, the words of the drawing amount of pelletron etc. are then comparatively convenient.Below, do explanation for these characteristics.

For example, as shown in figure 47, in the time will toilet bowl flush device 10 being installed, hole cover 98 can be set, make connecting line 76 in advance by the hole cover.

Also can regulate the setting angle of toilet bowl flush device, make it be applicable to various forms of low level cisterns by in installation portion setting " inclination pad " to low level cistern.That is to say, when the form of low level cistern is different, rinse mode difference not only, the structure of low level cistern is also scarcely identical simultaneously.Under situation like this, as shown in Figure 1, select any of multiple rinse mode in the control part 500, cooperate the structure of low level cistern simultaneously, might need to regulate the setting angle of toilet bowl flush device 10.Under situation like this, by using " inclination pad ", just can be reliably and easily regulate the setting angle of toilet bowl flush device 10.

Figure 48 is the assembling drawing that toilet bowl flush device is installed on the program of low level cistern by the inclination pad.

Just, the screw lock protuberance 20 of toilet bowl flush device 10 is inserted the opening 202 of low level cisterns 200, utilize

pad

90,91 clamping low level cisterns 200 and it is locked by nut 92.At this moment,

pad

90,91 shown in 48 figure, may be made in the thicker other end of an end than thin skewed " the inclination pad " that be respectively.

Figure 49 is the part profile that will use the installation portion of the toilet bowl flush device of inclination pad to be amplified.

By use on its thickness, be provided with distribution " inclination pad " as

pad

90,91, can allow relative angle with respect to the axle C of the toilet bowl flush device 10 of low level cistern 200 walls, in the specific direction specific angle that only tilts.Its result can be adjusted to the configuration relation of toilet bowl flush device 10 angle of the best in low level cistern 200.

For example, general low level cistern 200 is a ceramic, in its fabrication schedule for " demoulding ", with side opening up or expand in the majority that the mode opened forms slightly.That is to say that the side of low level cistern 200 is not to be parallel to vertical direction, but tilt.Under situation like this, as shown in figure 49, fix by

inclination pad

90,91, the mode that just can be level with the axle C of toilet bowl flush device 10 is installed.

This type of

inclination pad

90,91 can be inserted in screw lock protuberance 20 with the different angles more than 2 kinds at least.That is,

pad

90,91 is formed into and can installs with respect to the specific angle of screw lock protuberance 20 rotations.Particularly, for example, pad 90 with respect to outstanding base portion 20B for inserting by every half-twist.Pad 91 is to insert in the mode that its projection 91P is sticked in screw lock protuberance 20 groove 20C (please refer to Figure 11: every 90 ° of settings).That is to say that pad 91 also is can every half-twist and be inserted in screw lock protuberance 20.

Its result can install by

inclination pad

90,91 is suitably rotated, thereby toilet bowl flush device 10 can be tilted be installed on the desired direction.

For example, Figure 50 shows pad 90 to dispose in the face of the thicker mode in right side, and pad 91 disposes to face the thicker mode in left side, and toilet bowl flush device 10 is installed on the assembling drawing of the program of low level cistern 200.

Disposed the inclination pad at 90,91 o'clock in mode so, shown in Figure 51 (a), in low level cistern 200 inside, toilet bowl flush device 10 can be installed in the mode that tilts towards the direction of arrow (in the face of the left side of figure).Its result can prevent to be arranged at the hand washing that covers of low level cistern 200 and cause interference etc. with bottom surface, other bleed off pipe parts such as (not shown) and toilet bowl flush devices 10 of being located in the low level cistern 200 of alms bowl (not shown).

Figure 48 to Figure 51 (a), only an illustration of the present invention.Except this example, for example, also can make the toilet bowl flush device 10 in the low level cistern 200, install to face right side or the oblique mode of inclination up.Shown in Figure 51 (b), also can be after loading onto operating handle 100, be used for the mode of paster of difference " greatly " and " little " and implement to stick.

The form of low level cistern in the change rinse mode, also must be regulated to the distance the pelletron bar 84 from the output shaft of toilet bowl flush device 10 not simultaneously mostly.So under the situation,, can omit separator 82 for the present invention.

Shown in Figure 52, pelletron bar 84 directly can be inserted the mandrel 80 of toilet bowl flush device 10, and fixing by pin 86.At this moment, can suitably be arranged on the mandrel 80 fixing in advance with ditch 80A, 80B etc.Just, fixing chimeric by this with ditch 80A, 80B and pin 86, can pelletron bar 84 is fixing reliably.By from many fixing with selecting the best among ditch 80A, the 80B, go for diversified low level cistern.

For shared part and reduce number of parts, comparatively ideal is pelletron bar 84 as shown in Figure 28 waits, and the leading section 82B that can be inserted in separator 82 installs, and simultaneously as shown in figure 33, also can be inserted into mandrel 80 and install.

For this reason, from fact the section configuration of the leading section 82B of separator 82 being made identical getting final product with the section configuration of mandrel 80.In other words, be the connecting portion 82B of separator 82 that mandrel 80 is inserted the patchhole shape (except for insert sleekly this dimensional tolerance that has, section configuration with mandrel 80 is identical in fact), make roughly the same getting final product with the section configuration of the leading section 82B of separator 82.At this moment, for mandrel 80 is inserted in separator 82 sleekly, the size of the patchhole of connecting portion 82B can be made big slightly than mandrel 80.The section configuration of the leading section 82B of the section configuration of mandrel 80 and separator 82, and must be identical, as long as under the degree that the insertion cave 84H that can make pelletron bar 84 described later can not insert rotationally, be essentially identical getting final product.

So set, pelletron bar 84 also can insert for the leading section 82B of separator 82 and fix, and also can insert simultaneously to be fixed on the mandrel 80.Consequently, can make component sharingization, when reducing number of parts, also can eliminate the problem of taking part etc. by mistake when constructing at the scene.

And, owing to can regulate output shaft 70 (or 72) from toilet bowl flush device 10 within a large range to the distance the pelletron bar 84, so not can with various key element interferences such as the bleed off pipe 260 that is arranged on low level cistern inside, water service pipe 270, can make pelletron bar 84 spinning movement sleekly.Consequently, by combined, and can provide the toilet bowl flush device of the low level cistern that is suitable for wide norm form with the handoff functionality of rinse mode.

Moreover in the present invention, by changing the installation direction of pelletron bar 84, the drawing amount that can make pelletron is variable.Below, about this point, describe with reference to Figure 53 to Figure 58.

Shown in Figure 53, no matter pelletron bar 84 is the direction towards A, or towards the direction of in contrast B, can both insert mandrel 80 and fixes.

Figure 54 is the ideograph that shows the structure of pelletron bar 84, and Figure 54 (a) is its vertical view, and Figure 54 (b) is a left view, and Figure 54 (c) is vertical profile, and Figure 54 (d) is a right view, and Figure 54 (e) is a upward view.

On the pelletron bar 84 of this specific embodiment, offer and roughly be criss-cross patchhole 84H.This patchhole 84H and mandrel 80 roughly be criss-cross section tabling, insert mandrel 80 and can prevent idle running.Because the section configuration of patchhole 84H and mandrel 80 is respectively rotation-symmetric 4 times, so Fig. 9 and Figure 10 as the aforementioned also can select a kind of from 4 kinds of setting angles arbitrarily.

And, in the present invention,, can make the drawing amount of pelletron that all variations are arranged by allowing the projected direction P of pelletron bar 84 be inclination with respect to the axis of symmetry of patchhole 84H.

Figure 55 is the ideograph that demonstrates the rotation angle range of toilet bowl flush device 10.Under the situation of this specific embodiment, when making the flushing water outflow of " little ", mandrel 80 is to rotate 80 ° towards the direction of arrow A, and when making the flushing water outflow of " greatly ", mandrel 80 is to rotate 110 ° towards the direction of arrow B.With respect to this, being used for of existing hand low level cistern implemented the anglec of rotation that " greatly " reach " little " various differences.

For example, shown in Figure 56, the anglec of rotation that has " greatly " of hand operating handle is 125 °, and the anglec of rotation of " little " is 65 ° a low level cistern (type i).On the other hand, the anglec of rotation that also has " greatly " and " little " is all 95 ° low level cistern (Type II).In the present invention, by allowing the installation direction of pelletron bar 84 reverse, can make toilet bowl flush device 10 be applicable to such arbitrary low level cistern.

Figure 57 and Figure 58 are the ideographs that shows the anglec of rotation when allowing the installation direction counter-rotating of pelletron bar 84.Just, these figure are the observed ideographs of direction from the arrow Z of Figure 55.

Under the situation of the shown installation direction of Figure 57, pelletron bar 84 is by tilting 15 ° towards the anticlockwise direction under vertical under neutral condition as shown in Figure 57 (a).When state makes the mandrel 80 of toilet bowl flush device rotate 80 ° toward the clockwise direction thus, then shown in Figure 57 (b) like that, the angle of inclination of pelletron bar 84 becomes to by being 65 ° of angles under vertical.

On the other hand, like that, when making mandrel 80 when counterclockwise rotating 110 °, the angle of inclination of pelletron bar 84 is by being 125 ° of angles under vertical shown in Figure 57 (c).

That is to say that when making pelletron bar 84 be installed on this angle direction with respect to mandrel 80, the action that can obtain roughly corresponding to " little " is 65 °, the action of " greatly " is the drawing amount of pelletron of 125 ° the anglec of rotation.

With respect to this, under the situation of the specific embodiment shown in Figure 58, pelletron bar 84 is inserted in mandrel 80 towards the direction opposite with Figure 57.That is to say, shown in Figure 58 (a) like that, pelletron bar 84 under neutral condition by tilting 15 ° towards the right rotation direction under vertical.When state makes mandrel 80 rotate 80 ° toward the clockwise direction thus, then shown in Figure 58 (b) like that, the angle of inclination of pelletron bar 84 becomes to by being 95 ° of angles under vertical.

On the other hand, like that, when making mandrel 80 when counterclockwise rotating 110 °, the angle of inclination of pelletron bar 84 is still by being 95 ° of angles under vertical shown in Figure 58 (c).

That is to say, when making pelletron bar 84 be installed on this angle direction, can obtain roughly to be all the pelletron drawing amount of 95 ° the anglec of rotation corresponding to the action that no matter is " little " or " greatly " with respect to mandrel 80.At this moment, shown in Figure 54 (a), like that,, can not assemble reliably just can not make a mistake direction of insertion if pelletron bar 84 is provided with the mark 84M that is used for discerning direction of insertion (reaching " C " being expressed as " E " with figure).

As mentioned above, in the present invention, insert by allowing pelletron bar 84 reverse with respect to mandrel 80, moreover, can allow its projected direction P tilt, and can change respectively corresponding to " greatly " drawing amount with the pelletron of " little " with respect to the axis of symmetry S of patchhole 84H.Consequently, when to make rinse mode be variable, actuating range also became variable, and the toilet bowl flush device that is applicable to various forms of low level cisterns can be provided.

More than for example of the present invention is illustrated with reference to specific embodiment.But the present invention is not limited to these specific embodiments.
